The Forums section allows you to interact with peers and professionals for help recognizing a font, or getting feedback on new fonts and logotypes. Plus, their grouping and categorizing of all those fonts makes it SO easy to find what you need.
Maybe we're a little biased... but these guys have been linking to our templates and resources for years. It's an online community of talented designers and pre-press professionals that share a wealth of knowledge. You can also get critiques on your current or past design projects. But it's not for the faint of heart; These guys are tough, fair, sometimes harsh, and the occasional noob will get owned! But still, it's a great resource for finding answers to just about any question.
If there's ONE thing better than an irreverent Aussie, it's MANY irreverent Aussies that knows a helluva lot about ART! These guys have daily updates about anything and everything going on in art, print, web, and design. Just this past week they covered events in their native Australia, over in Morocco, an all the way up to Portland, Maine! They don't miss a beat, and neither should you!

Who doesn't love Photoshop?! EVERYONE knows how cool it is, but let's face it... unless you're a graphic designer or pre-press professional with at least 5 years of solid experience, then you haven't even STARTED to scratch the surface.

Fortunately, the folks at Psdtuts+ have a TON of easy-to-follow tutorials on every possible effect and technique. Definitely a "Must-Bookmark" for your browser.
